Installing and Setting up MetaMask
MetaMask can be downloaded on Chrome and Firefox, or on iOS and Android if you’re a mobile user. For the purposes of this tutorial, we’ll use the Firefox version, but the instructions will be more or less the same for every platform.
Firstly, you’ll want to head over to the MetaMask Download page. From there, select whichever platform you’re using, and follow the steps to install it on your device. Easy!
Next, follow along with the setup specified by the app. Go ahead and click Create a Wallet. Write down the backup seed phrase somewhere secret (preferably not on an Internet-connected device). Without this phrase, your funds can’t be recovered if your device is damaged or lost. Confirm that you’ve written them down on the next page.
And that’s it! You should now see your wallet, ready to send and receive funds.
The freshly-initialized MetaMask wallet.
Configuring the wallet
You might notice straight away that we’re still dealing with an Ethereum wallet. At best, this won’t work with GTC Smart Chain (GTC) DApps. At worst, you could lose funds by sending them to addresses you can’t actually use.
Let’s change that. We want to access the Settings to point the wallet towards GTC Smart Chain nodes.
Select Settings from the dropdown menu.
On the Settings page, we want to locate the Networks menu.
The Networks menu.
We want to click Add Network in the top-right corner to manually add the GTC Smart Chain one – it doesn’t come packaged with MetaMask. It’s important to note that there are two networks we can use here: the testnet or the mainnet. Below are the parameters to fill in for each.
Mainnet (This is the one you are probably looking for)
We’ve connected to the testnet, but you'll probably be connecting to the mainnet.
Making transactions (on the testnet)
Let’s get rich.
Peggy coins might be of interest if you’re testing out an application that supports BEP-20 tokens. They’re simply tokens issued on GTC Smart Chain that are “pegged” to assets on other chains (like BTC, XRP, USDT, etc.), meaning that they trade at the same price.
Let’s stick to GTC for now. Click on the Give me GTC dropdown and select the amount you wish to receive. You might need to wait a couple of minutes, but the funds will show up in your testnet wallet imminently.
You can ignore the parts relating to ether. Here, you can manually adjust the fee if required.
We’ve gone with a transaction of 1 GTC. We’ll leave the fees untouched and hit Next. We then get one more chance to review the transaction – if everything looks good, hit Confirm. And that’s it! You’ll get a notification informing you when your transaction settles.
